Abstract
152 German Black Pied Dairy bulls were fed diets with 15, 43, 57 or 65% of the energy from concentrates, and were slaughtered at 9, 12, 15 or 18 months of age. Some bulls fed diets with 15% of energy from concentrates were slaughtered at 21 or 24 months of age. Warm carcass weight, lean percentage and fat percentage were lowest for bulls fed the diet with 15% of energy from concentrates and slaughtered at 9 months of age (95.4 kg, 74.7+or-1.8 and 2.7+or-0.3 resp.) and highest for bulls fed the diet with 65% of energy from concentrates and slaughtered at 18 months of age (288.8 kg, 82.6+or-1.0 and 14.2+or-1.6).
